Миграционный баланс российских городов: к вопросу о влиянии размера и положения в системе центро-периферийных отношений
Basing on the data of migrant population surplus/decline in Russian cities for the period 1991-2009 the attempt is made to evaluate the impact of the population size of a city as well as the city position in the system of central-peripheral relations on its migration balance. The author also explains the existing migration mobility pattern through hierarchy of cities within a region.
In the present paper, on the basis of the theory of production principles and production revolutions, we reveal the interrelation between K-waves and major technological breakthroughs in history and make forecasts about features of the sixth Kondratieff wave in the light of the Cybernetic Revolution that, from our point of view, started in the 1950s. We assume that the sixth K-wave in the 2030s and 2040s will merge with the final phase of the Cybernetic Revolution (which we call a phase of self-regulating systems). This period will be characterized by the breakthrough in medical technologies which will be capable to combine many other technologies into a single complex of MBNRIC-technologies (med-bio-nano-robo-info-cognitive technologies). The article offers some forecasts concerning the development of these technologies.
Subject Pursuing the socio-economic policy in regions requires understanding the processes of concentration of resources, population, enterprises in certain territories, mostly, in cities. Recent studies show increasing interest of economists in the Zipf's Law manifestation in the regional system, and cities distribution under the rank-size principle.
Objectives The aims are to test the Zipf's Law in Russian cities, to support or reject the hypothesis that in Russia the Zipf coefficient depends on the size of the geographical territory of the federal district.
Methods We used the least square method to analyze the Zipf's Law in Russian cities in general, and in each federal district, in particular. The sampling includes 1,123 Russian cities with population over 1,000 people in 2014. Results The Zipf's Law manifests in the entire territory of the Russian Federation. In federal districts, the Zipf coefficient ranges from -0.65 (the Far Eastern Federal District) to -0.9 (the Ural and North Caucasian Federal Districts). The analysis of the sampling of cities with population over 100 thousand people demonstrated -1.13 Zipf’s coefficient.
Conclusions The test of the Zipf's Law for Russian cities shows that it is valid for small (8,600-15,300 people) and large cities (66,700-331,000 people). The Zipf's Law fails for cities with population exceeding one million people (except for the city of St. Petersburg). The study supports the hypothesis on dependence of the Zipf coefficient on the size of a federal district.
